Customer Question

I have a 2007 Land Rover LR3 4.4 liter V8 with cruise control problems. It does not hold the setting and turns itself off. I wonder if it is a common probelm with a cracked vacuum hose and where I should look.

Hello,
I'm Shantal and I'm a moderator for this topic.
I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.
I was checking to see if you had already found your answer or if you still need assistance from one of the Professionals.
Please let me know if you wish to continue waiting or if you would like for us to close your question?
Thank you,
Shantal

Hello
the engine on this one uses an electronic throttle so there's no vacuum actuator to look for, its all self contained
I'd suggest removing the air intake so you can see the throttle blade and with the ignition on and the engine off have your assistant slowly push down on the throttle pedal whilst you watch the throttle
it should open smoothly and slowly with no sudden jerks or steps
if it does do this then check over the wiring for damage or corroded connections and if OK consider replacing the throttle body
